Somewhere, a 64-year-old is doing math.
Corpus built. Withdraw 4% a year. Bump it for inflation. Relax.
It feels like science. It is actually folklore, and it was written in a country that is not yours.
Where the number came from
In 1994, an American financial planner named William Bengen tested a simple idea against US market history going back to 1926. Could a retiree pull 4% in year one, raise it with inflation every year after, and not run out over 30 years?
The answer, in American data, was yes.
That single finding became the most quoted rule in personal finance on earth. The problem is hiding in three words: in American data.
The study nobody quotes in India
In 2010, Wade Pfau took Bengen’s exact rule and ran it across 17 to 19 developed countries over 109 years of market history. Not opinions. Returns.
The result should be printed on every retirement brochure.
With a balanced 50/50 portfolio, the 4% rule survived in zero of those countries.
It came close only in the US and Canada. Everywhere else it cracked. In more than half of the countries, including Italy, Spain, France, Germany and Belgium, a retiree following 4% would have run dry before 30 years. Italians faced failure roughly 80% of the time.
And Japan, the cautionary tale every long lived saver should fear, supported a worst-case withdrawal rate of just 0.27%. At that rate, your ₹5 crore funds about ₹1.35 lakh a year. Not a typo.
The twentieth century in the US was the winning lottery ticket. We took the winner’s strategy and assumed it was the rule of the game.
India has no clean 100-year equity record. We have higher expected returns, yes, but also higher volatility and a far shorter history. Importing 4% is not importing a method. It is importing somebody else’s good luck and calling it a plan.
Even America has quietly downgraded 4%
Here is the part that ends the debate.
Morningstar now runs this calculation every single year. Their safe starting rate for a 30-year US retirement was 4.0% in 2023, fell to 3.3% in 2021 when valuations were stretched, and sits at 3.9% today.
Read that again. In the country the rule was built for, the experts who study it most closely no longer trust a flat 4%. They move the number as conditions move.
So when an Indian advisor hands you 4% as a fixed law of nature, they are quoting a number that its own homeland has stopped treating as fixed.
The expense that breaks Indian retirements
Now the part that is uniquely, brutally Indian.
When you “adjust for inflation,” which inflation do you mean?
General inflation in India runs around 5 to 6%. Fine. But your retirement is not bought with a general basket. In your seventies and eighties, it is bought disproportionately with healthcare. And healthcare inflation in India is running at 13 to 14% a year, the highest in Asia, roughly triple the headline number.
Compounding does the rest, quietly and without mercy.
A surgery that costs ₹5 lakh today, growing at 14%, becomes about ₹18.5 lakh in 10 years and nearly ₹69 lakh in 20 years. That is the single bill most likely to land exactly when you are oldest, most fragile and least able to earn.
Your 6% inflation adjustment is a comforting fiction for the one cost that matters most at the end. You are indexing your groceries and ignoring the ICU.
The first five years decide everything
There is one more trap, and it is about timing, not size.
A bad market run in the first few years of retirement does damage that a good run later cannot repair. You are selling units to live while prices fall, so you sell more of them, and there are fewer left to recover when markets turn. Research consistently shows a weak opening stretch can shorten a portfolio’s life by more than 20 years.
The flip side is the hopeful part. Morningstar’s data shows that a retiree who clears the first five years with gains sees the subsequent risk of running out drop to around 4%.
Same corpus. Same withdrawal. Two completely different retirements, decided almost entirely by which five years you happened to retire into. You do not control that. So you plan around it.
The “be flexible” advice everyone gives and nobody follows
The standard fix is “withdraw more in good years, cut back in bad ones.”
It is correct. It is also a fantasy for most humans.
Even Morningstar’s own researchers concede that almost no retiree will calmly slash their income the year the market falls. Picture telling yourself, at 73, that this is the year you travel less, eat out less and downgrade the car, because the Nifty had a bad January. You will not do it. Your spouse will not let you. Discipline is not a retirement strategy. It is a hope.
So stop relying on willpower. Rely on architecture.
Build the system, not the number
Here is the structure we would actually defend.
A guaranteed floor. Your non-negotiable monthly expenses, rent, utilities, food, basic medicine, should be covered by income that does not care what the market did this morning. Annuities, bonds, a laddered fixed income sleeve, government schemes. Boring on purpose. This is the part you must never have to “be flexible” about.
A separate medical buffer. Not a line in your general corpus. A dedicated pool, plus health cover sized for tomorrow’s bills, not today’s, because it must grow at 13 to 14%, not 6%. Treat your insurance sum as a depreciating asset and top it up on schedule.
Only the surplus is market-linked. The equity-exposed portion funds lifestyle, travel, and the good years. This, and only this, is where you flex. When markets are strong, spend it. When they are weak, the floor still pays your bills, so cutting back here is annoying, not frightening.
A review every single year. Not to panic. To recalibrate, the way Morningstar moves its numbers as conditions change.
That is the whole game. A floor you never touch, a medical pool that outruns medical inflation, and a flexible top layer that absorbs the market’s mood so your dignity does not have to.
The real question
So no, the question was never “Is ₹5 crore enough?”
It was not even “Will this last 30 years?”
The real question is sharper, and it is the one that separates a number from a plan:
Which part of my retirement am I willing to leave at the mercy of the market, and which part will I refuse to?
Answer that, and you are no longer retiring on a borrowed American number from a lucky century.
You are retiring on a system built for the country, the lifespan, and the medical bills you will actually face.
